This mask has become a worldwide symbol of anti-capitalist protest. Its copyright is held by the Time Warner Corporation. It is made in CHINA.

This is V’s mask. V is the fictional revolutionary anarchist in V for Vendetta, a 2006 film based on comic books by British writer Alan Moore. In 2008, hackers belonging to the group Anonymous wore the mask in public to conceal their identities offline, and in 2011, it suddenly became the predominant symbol of the global Occupy protests – a unifying face for a movement without leaders or heroes. More than 100,000 of the US$10 masks were sold in 2011, and for each one sold, royalties were sent to the makers of the movie, Time Warner. This is V’s mask, but it is owned by the world’s largest media conglomerate.

The demands of the 2011 Occupy protests varied: in New York, protestors demanded that bankers take responsibility for the financial crisis, while demonstrations in Moscow focused on allegations of electoral fraud. But each confronted social and economic inequality, and the Occupy slogan resonates everywhere – “We are the 99 percent” was originally directed at the richest one-percent of US citizens, who own almost 40 percent of the country’s wealth. Globally, the wealthiest 20 percent of mankind controls 83 percent of the world’s wealth, compared to the poorest 20 percent, who share one percent of it between them.

It's a deep-breath moment in the history of technology as Solar Impulse soars to the skies.

Because, pinch yourself, solar power is predicted to become the dominant source of electricity globally by 2050.

The price of solar electric panels fell 70% in recent years and costs are expected to halve again this decade.

And Deutsche Bank forecasts that, based on current fossil fuel prices, solar will produce power as cheaply as gas in two thirds of the world before 2020.

In the UK the solar industry thinks it can compete with wind within 18 months and with gas in the near future. In the USA, solar jobs already outnumber coal jobs.

The solar revolution was sparked by government subsidies, which attracted venture capitalists to fund innovation and created a huge market that Chinese manufacturers are battling to exploit.

The solar boom is a huge help in the battle against climate change, but scientists warn it's not nearly enough. And we must find ways of storing that mighty but capricious power, and making it work with the grid.

Despite bringing joy to millions of coffee-craving people every day, John Sylvan, creator of the Keurig coffee maker, regrets his invention due to the amount of waste it generates.

To this day Sylvan does not understand consumers 'slavish' addiction to the pods, which he finds, "Rather expensive." When Sylvan developed the product, he thought it would mainly be used in offices -- but that hasn't been the case. According to the Atlantic, one in three U.S. homes owns a pod-based coffee machine.

As many as 40 per cent of Canadian homes use them, and the non-recyclable, non-biodegradable waste they generate are extremely unpopular among environmentalists. "I don't know why people have them in their house," Sylvan told the CBC, adding that consumers should consider purchasing eco-friendly alternatives. Sylvan worked at Keurig during the 1990s. He thought he Keurig would be a benefit to office dwellers, enabling them to grab a cafe-quality drink without having to venture outside. "That would make it environmentally neutral, because you wouldn't have those Starbucks cups [everywhere]," Sylvan told the CBC. But the popularity of the product negated his intention, quickly morphing into a massive generator of plastic waste. Sylvan left the company in 1997 and sold his ownership to Keurig Green Mountain for $50,000. Today, the company sells billions of plastic K-cups each year, with Canadians spending $95 million in 2014 on single serve coffee products. In 2013, 8.3 billion K-cups were produced. Keurig Green Mountain says it plans to have its cups fully recyclable by 2020, but Sylvan tells the CBC he's skeptical of the plan. "There's other ways to do it, but they're not exploring other ways to do it," he says. "They're going to make those little plastic cups forever, because they can't think outside the box."

PLASTIC COFFEE PODS AND THE ENVIRONMENT: Plastic coffee pods can degrade to form microplastics, which can migrate into waterways and pose a threat to wildlife. While all the components used to create a K-cup are recyclable individually, the product cannot be recycled when combined into a single unit. The cups can take up to 50 years or more to degrade in a landfill.
